Common Problems & Known Issues

The 2008 Chrysler Aspen is a badge-engineered Dodge Durango built on the aging DN platform. These trucks share Durango's drivetrain weaknesses—particularly catastrophic HEMI engine failures and transmission cooler issues that destroy both the trans and radiator when they let go.

5.7L HEMI Lifter/Cam Failure Leading to Complete Engine Destruction

Common · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Cold-start ticking or tapping that persists after warm-up, MDS (cylinder deactivation) system throwing P3401/P3425 codes, Sudden loss of power with metallic knocking, Metal shavings in oil, dropped valves destroying pistons and cylinder walls
Fix: Early HEMI engines suffer collapsed lifter rollers that chew up cam lobes, drop valves, and score cylinder walls. Once the knock starts, it's too late—you need a complete engine rebuild or replacement. We're seeing 40-60 hours of labor for a proper rebuild including machine work, all new bearings, pistons, rings, heads, cam, lifters. Many shops just swap in a reman long block to save diagnosis time.
Estimated cost: $6,500-11,000

Transmission Oil Cooler Failure (Radiator Internal Cooler)

Common · high severity
Typical onset: 70,000-120,000 mi
Symptoms: Strawberry milkshake-colored fluid in radiator or transmission, Transmission slipping, delayed engagement, or complete failure, Coolant loss with no external leaks, Engine overheating after transmission issues develop
Fix: The factory radiator has an internal trans cooler that ruptures, mixing ATF and coolant. This contaminates both systems and destroys the transmission within days if driven. Proper fix requires new radiator, external trans cooler, complete trans flush (often a rebuild since contamination damages clutches/valve body), coolant flush, all hoses. Figure 12-18 hours if the trans needs a rebuild, 6-8 if you catch it immediately.
Estimated cost: $2,800-5,500

Rear Differential Pinion Bearing Failure

Occasional · high severity
Typical onset: 90,000-140,000 mi
Symptoms: Whining or howling from rear that increases with speed, Clunking when shifting from drive to reverse, Grinding noise during acceleration, Gear oil leak from pinion seal area
Fix: The rear diff pinion bearings wear prematurely, especially in 4WD models that see towing. Once the whine starts, the bearing is already eating the ring gear. Needs complete differential rebuild with new carrier bearings, pinion bearings, crush sleeve, and often ring-and-pinion if caught late. Setup requires precise shimming and torque specs. 6-9 hours labor.
Estimated cost: $1,800-2,800

4.7L V8 Valve Seat Recession and Head Gasket Failure

Occasional · high severity
Typical onset: 100,000-160,000 mi
Symptoms: White smoke on cold start that clears up, Coolant loss with no visible leaks, Misfires on multiple cylinders, Overheating and bubbles in coolant reservoir
Fix: The 4.7L PowerTech engines drop valve seats due to inadequate interference fit from the factory. This leads to compression loss and head gasket failure. Proper fix is both heads off, hardened seat inserts machined in, new gaskets, timing chains (while you're in there), water pump. Machine work adds cost. 18-24 hours total.
Estimated cost: $3,200-4,800

Front Lower Control Arm Ball Joint Separation

Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunking over bumps from front suspension, Wandering or loose steering feel, Uneven tire wear on inside edge, Visible play when prying on ball joint with wheel off ground
Fix: Ball joints wear rapidly and the press-in design allows them to pop out of the control arm socket, causing immediate loss of control. Chrysler issued TSB 02-001-07 but never recalled them. Replace both lower control arms as assemblies (ball joints aren't serviceable separately on these). Always do alignment after. 3-4 hours labor.
Estimated cost: $650-950

Exhaust Manifold Bolt Breakage and Leak

Common · low severity
Typical onset: 50,000-90,000 mi
Symptoms: Loud ticking from engine bay that changes with RPM, Exhaust smell in cabin, Visible soot streaks on manifold, P0430/P0420 catalyst efficiency codes from leak affecting O2 sensors
Fix: Manifold bolts corrode and snap flush with the head due to heat cycles and dissimilar metals. Requires drilling out broken studs, often multiple per side. On the HEMI, the rear manifolds require removing engine mounts and jacking the engine for access. Budget 6-9 hours if multiple studs are broken and you're drilling/helicoiling in-place. New manifolds and gaskets recommended.
Estimated cost: $800-1,400

Transfer Case Mode Actuator Motor Failure

Occasional · medium severity
Typical onset: 70,000-130,000 mi
Symptoms: Service 4WD light illuminated on dash, Grinding or clicking from transfer case area, Unable to shift into 4WD or stuck in 4WD, Codes C121C, C2204 for transfer case shift motor
Fix: The electric shift motor on the NV245 transfer case seizes or strips internal gears. Motor itself is external and takes about 2 hours to replace. If the problem went unnoticed and the driver forced it, internal shift fork damage requires case disassembly, adding 6-8 hours.
Estimated cost: $450-850
Owner tips
  • Install an external transmission cooler immediately and bypass the radiator's internal cooler—this single $300 mod can save you $5,000
  • On HEMI models, switch to 0W-40 full synthetic and disable MDS with a tuner if you're keeping it past 100k—lifter failures are epidemic
  • Inspect ball joints every oil change starting at 50k miles; pry bar test takes 2 minutes and can prevent a crash
  • Budget $1,500/year for deferred maintenance issues starting at 100k miles—these trucks nickel-and-dime you after the powertrain grenades
Hard pass unless you're getting it for $3,000 under book value with full service records showing the trans cooler and MDS issues have been addressed—these are money pits waiting to strand you.
